Surface Clutter Reduction for Ground Penetrating Radar
JMECS, 2021 Surface clutter is one of the problem in GPR survey that may caused the difficulty in detecting object. The rough of the ground surface caused the surface clutter is a method for reducing the clutter is need to improved the detection result. One of method is used to achieve that objective is averaging method.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
